Thanks for the reply. I take it from all who has used this material before that a primer really should not be used with this material as a base. I have always used this epoxy primer under everything that I have sprayed and have never had any trouble in 25+ years. I sure that Eastwoods material is a top notch material and will probably try this at some later date on another project. But for now I think that I'll just peal the remaining material off and instead of having everything sandblasted again, just use chassis saver that I know will hold over the primer that is already on these parts. Live and learn. I'm going to contact Eastwood's rep just to see what he has to say on this anyway. Again, thank to everyone who has replied to my problem that I have had with this and good luck with all of your projects.
